I've found the idea of unikernels interesting for several years now, is there a tl;dr on why they don't seem to have taken off, like at all? Or is it all happening behind some doors I don't have access to?

I think that part of it is that relatively few people use bare-metal servers these days, and nested virtualisation isn't universally supported. I also found this technical critique [0] compelling, but I have no idea if any of it is accurate or not.

		When I first heard about unikernels my hope/thought was that people would go back to using more bare-metal servers for unikernels.

		there is a workaround for nested virt requirements. you can use PVM patch and para-virtualization. I've seen several startup using that approach to be able to create VM on small/cheap EC2 instances.

They kind of did, that is basically how serverless works.

Managed runtimes on top of hypervisors.
